"A latching solenoid control circuit uses brief (20–50ms) voltage pulses to toggle between states, reversing polarity to switch between locked and unlocked. It requires an H-bridge or DPDT relay setup to manage current direction, providing high efficiency by eliminating continuous power consumption."Mon, 06 Apr 2026 23:49:00 GMThttps://forum.allaboutcircuits.com/threads/self-latching-circuit.209626/Hey guys, I need to build up the circuit that : 1/ when main power 5V is connected for the first time, MCU gets 5V (first time autostart). 2/ MCU starts and drive the PMOS switching on by active high signal via BJT. 3/ When you push momentary switch - it sends the pulse to MCU input signal...Wed, 01 Apr 2026 08:31:00 GMThttps://forum.allaboutcircuits.com/threads/suggestions-required-for-operation-of-set-on-a-latching-relay.199150/How to get the SET to work in the attached by-directional motor control circuit. To SET; Switch Position must be in UP position not the DWN position. The magnetic reed switch RESETs the latching relay at the end of the UP movement of the motor drive. Once this happens the latching relay will...Thu, 02 Apr 2026 10:18:00 GMThttps://forum.allaboutcircuits.com/threads/latching-relay-that-resets-when-the-power-is-cycled.196102/Using a standard Non Latching relay, here is a latching circuit that seals in the relay with the D2 diode and a second set of relay NO contacts. SW1 can be a momentary NO button but once the power is removed from the circuit the realy coil will drop out and open the RLA/2 seal in contacts. Voltage depends on what is required by the relay up to ...Wed, 08 Apr 2026 07:55:00 GMThttps://forum.allaboutcircuits.com/threads/simple-latching-relay-with-momentary-power-trigger.199044/I have a simple question that I cannot, for the life of me, solve. The premise is simple: I need to turn ON/LATCHING relay using a momentary programmed switch that closes and supplies 12vdc for 25ms, and have it stay LATCHED until the same programmable switch closes again for 25ms, providing...Wed, 08 Apr 2026 14:28:00 GMThttps://forum.allaboutcircuits.com/threads/solid-state-latching-relay.203958/I have a latching relay set up that is working well but I would like to switch it to a solid state circuit. Can anyone help me with this? I really just don't have the experience or expertise to do it. But I really would like to understand how to do it.

And it will change its sate again only when power is turned on again according to the pulse it gets after the power is on. what kind of a circuit will help in this? thanks in advance.Tue, 07 Apr 2026 17:50:00 GMThttps://forum.allaboutcircuits.com/threads/latch-circuit-single-button-switch-on-off.198016/It's been ages since I drew a FF circuit and even longer since I've debounced a switch. But this is what I was thinking: 1 switch 3 resistors 1 cap 1 NPN BJT 1 chip (CD4013) or equivalent. Doesn't need to be high speed so no 74HS series chips. And if I've debounced the switch properly (quite possibly wrong) it should result in a very high reliability circuit without the sensitivity to noise.Wed, 08 Apr 2026 14:57:00 GMThttps://forum.allaboutcircuits.com/threads/building-a-latching-relay-circuit.181533/Any relay with spare NO contacts can be wired to latch. Connect the contacts across the pushbutton. When the button is pressed the contacts will close and continue to energize the relay even after the pushbutton is released. To reset the relay, install a NC button in-line with entire circuit or relay or latching contacts to break the power to the relay coil.Wed, 08 Apr 2026 04:13:00 GMT
